The Rap guanine nucleotide exchange factor (GEF) 4 ELISA kits listed below utilize specific antibodies for the plate-based assay of Rap guanine nucleotide exchange factor (GEF) 4 in various samples. Rap guanine nucleotide exchange factor (GEF) 4 is another term for the RAPGEF4 gene, which encodes the protein, Rap guanine nucleotide exchange factor 4 in humans. It has been reported that Rap guanine nucleotide exchange factor (GEF) 4 plays a role in adaptive immune responses and GPCR signaling pathways, among other functions. Structurally, the RAPGEF4 protein is 1011 amino acid residues in length and 115.5 kilodaltons in mass. However, as many as 5 protein isoforms have been identified. It is localized to the membrane and cytoplasm of the cell. In terms of tissue specificity, it is reported to be highly expressed in the brain and adrenal gland. Other names for this target antigen include CAMP-GEFII, CAMP-GEFII, and CGEF2.
Some Rap guanine nucleotide exchange factor (GEF) 4 ELISA kits can detect targets at levels as low as 0.156 ng/mL and as high as 10 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
